Question

(x+1)^2 - 4x = (x-1)^2

Answer 1

Step-by-step explanation:

x^2+1+2x-4x=x^2+1-2x

2x-4x=-2x

-2x=-2x

x=0

Answer 2

Answer:

Hence (x+1)²-4x=(x-1)²  proved

Step-by-step explanation:

Here we have been given an equation and it has been asked to prove whether the LHS= RHS or not. For this, we will simplify the above-given expressions and solve them to see whether it is equal to the RHS or not.

For proving this we first simplify the LHS as follows;

LHS= (x+1)² -4x

⇒ x²+2x+1-4x

⇒ x²-2x+1

⇒(x-1)² = RHS

Hence proved.

Therefore the above-given expression is proven.
